Six months ago, Kate’s twelve-year-old daughter Melanie disappeared. It’s been six long months since Kate identified her battered, lifeless body. Kate is only just beginning to come to terms with her daughter's murder when a sinister message appears on her computer screen: WHY DID YOU LET HIM HURT ME, MUMMY? More horrifying messages follow. Only one person could be doing this to Kate—Melanie’s murderer. Chief Inspector Harmon focuses his enquiries on Kate’s abusive ex-husband David and her colleague, computer whizz-kid Adam Shepherd. Kate has already lost the one thing that gave her life meaning. So now she decides to fight, but can she unmask the killer before he wrecks what’s left of her life?
